I installed the Power Ccmmander iii usb and hi flow airfilter prior to taking a 1500 mile run down the Oregon coast to Calif and back up I-5 to Washington. The increased preformancewas very aparent, going through the mountain passes with no hesatation , gas millage was excelent,, I now have approx 26k on the bike and love it runs strong. will be taking it down south next summer.

This is a great product. The past few years I've nothing but great things about Dynojet. The power commander is worth the investment. Not to mention adding some giddy up to your pony. Thanks Dennis Kirk!

Installed and downloaded the right map for my bike. After a test ride did a few minor adjustments the the map. It feels like I'm riding a new bike. Had been having problems since I went to Cobra straights from the stock 2 into 1 Yamaha pipes and this fixed it up. Runs better than it did new.Dennis Kirk had the best price on the web for the part. Saved me about $25. Very fast shipment.

Dennis kirk is the best in products and service . The power commander installation was straight foward and had it on my Meanstreak in a couple of hrs. It took my little brain more time too absorb the installation info,than it did too do the installation.The bike works a lot smoother and more balls. Well worth the dollars spent
